Do you have any idea what occupation Andrew BROWN or John COMPTON might have undertaken?
I have found an Andrew BROWN on the Jury lists for 1857, 1858, 1859, occupation given as a "licensed victualler", residing on Lambton Quay.
There is also an Andrew BROWN, a labourer, living on Porirua Road - he appears in the 1856 - 1859.
There is also entries for 1856-1859 for a John COMPTON, carpenter, living on Lambton Quay.
Do any of these sound likely matches for your men?
